Something USD and plastic but with parts availability would be nice. I'm just connecting it to this Calypso for a beach diving and travel beater. By the way on the Calypso (off topic) my first stage has holes instead of flats in the spring retainer. Which years did AL use pin spanner holes instead of wrench flats?
Let me know what second stages in disco yellow or black plastic you might like to trade straight across
Thanks, Ron
